Yup. I have no rain gutters, and mulch beds around the house.
I used 4 inch chopped stone where the mulch beds are level and 8 inch where the ground slopes and I make the mulch deeper on the outside of the mulch beds.
I have the stones on a base of crushed granite. I've found they last longer if I mix in a small amount of mortar in the crushed granite.
Houston has such heavy rains plus hurricanes, so I'm learning how to make the landscaping more durable.
With time and reworks, I'm adding more and more of the 8 inchers.
The stone is called Cherokee. My back and front porches are covered with Cherokee and hickory field stone 1" thick.
It gets mildew and blacken every year. Used to power wash it every year, but found wet and forget which works great here in Houston. I put it on the brick, stone and roof (which is metal with teal colored stone on it).
We've lived here 27 years and really are proud of the landscaping and house in general.
